Special demands apply to lacquers and paints designed for furniture. Requirements for stackability, fast drying and resistance to blocking, solvents, chemicals and UV light all call for a thorough understanding of binder technologies. Akzo Nobel Resins has developed a range of waterborne binders that allow our customers to formulate environmentally compliant furniture coatings. In this paper, two new product ranges for the industrial wood coatings market are highlighted — one-pack, self-crosslinking acrylic dispersions; and waterborne, 2K, non-isocyanate systems.
When applying conventional solventborne coating systems on an industrial coating line, organic solvents are released into the earth’s atmosphere. To comply with European legislation, these emissions must be reduced by using expensive and complicated technical equipment and techniques such as solvent recovery, post-combustion, etc. Waterborne coatings contain very low quantities of solvents, or none at all. They allow for solvent-emission abatement by approximately 90%, provide a better working environment for the applicators and drastic pollution reduction.
